摘要
论述了全微机化便携式电能表校验仪的设计思想、基本算法，介绍了硬件电路工作原理及软件框图。本校验仪中基于采样原理的软标准表取代了模拟电子电路构成的硬标准表，促进了国内便携式电能表校验仪的发展。
This paper discusses the design idea and algorithm of fall microp rocess orism portable instrument for testing electricity meters, and introduce princi pies of the hardware system and main program blocks. The traditional hard standard meter is replaced by the soft standard meter based on digital sampling in the instrum ent. The refor, a new approach has been derived in the development of portable testing instrum ent for our country.
